How To Hide Rows 2-5, 7-10, 12-15 Etc

I'm creating a roster which effectively needs 5 discrete pieces of information per cell - one main piece and 4 notes.

The creator of the current worksheet used comments for this function. They can't be printed, searched etc, you can't work with them and because the info can't be added with data validation it's inconsistent. What a nightmare.

I've rejected the 3d option across sheets because of the complexity and limitations of 3d calculations.

My solution is to have the main info in row 1 and the other 4 items in rows 2-5 and then repeat downwards so there are 5 rows per day.

My question is this - is there an easy way for users to hide and unhide the 4 extra rows? I need to improve readability but the extra info needs to be quickly and easily accessed by some users. Everyone else just needs to see what they are doing each day. This roster is a year long downwards so manual hiding and unhiding rows isn't practical.

e.g.:

and when hidden, this:
